lie it known that leis}: lil. liner, a citizen "rates of .finierica.residing at ecatine. in the county of l rscatine and s out Iowa. hasinvented ce in new and fill improvements in Vei'itilated Corncribs, ofwhich the following is a specification.

This application is a continuation of my former application, Serial llo. 331,763 filed October 20. 1919.

My invention relates to corn cribs and more particularly to improvementsin constructing cribs whereby ventilated spacer elements are interposedbetween the staves of the conventional concrete silo.

The object of my invention is in the provision oi a ventilated corn cribby means of interposed spacer elements between the op posed ends ofadjacent staves.

Another object of my invention is in the provision of a simple spacerelement which may be used in conjunction with the conven tional silostave to form a ventilated crib.

A further object of my invention is in the particular form of my spacerelement which is capable of engaging, in a substantial manner theopposed ends of adjacent staves and at the same time providingsuiiicient ventilation therebetween without detracting from the strengthof the total structure.

Other objects of my invention will appear in the following;specificationin connection with the annexed drawings in which:

Figure 1, is a fragmentary vertical section of the crib structureshowing the actual po.- sitioninp; of the spacer elements.

Figure 2. is a detail vertical section oi one of the spacer elementsinterposed between adjacent staves.

Figure 3. is a pers 'iective view of the spacer element and Figure t, isa detail horizontal sectional view showing? the engagement of the spacerelement with laterally adjacent staves.

In Figure 'l of the drawings. in which I have shown a fragmentaryelevation of the corn crib. a base a is shown. This base portion is ofconcrete. although some other material might well be used inasmuch asthere is only the necessity of providing a substantial and levelsupportfor the stave members. The staves 10 form the major part 01 thewall structure of the crib and are of 331,?53, filed fictober 20, 1919.Thisapplication filed March 27, 1922. Serial No. 547,008.

conventional stave form, being comparai'ely long and narrow and of athickness to correspond therewith These staves are arranged insuperposed courses and in break joint relation as l: have'shown inFigure 1, this structure providing a maximum of emciency not only as tostrength but as to ease of construction. As shown in Figure 4 the si esof the staves are concave and convex respectively, with the result thata cylindrical structure may be formed and the staves intained withoutthe use 01 cement. ans for supporting the stave members is vided in thetie rods 11.

The structure I have so far described is merely that of the conventionalconcrete stave silo but the essence of my invention lies in thefollowing element:

This member has the longitudinal bars 1.2 which in connection with theend or head portions '3 provide the ventilating portions. Projecting);cars 14 on the head portions engage, as shown in the various figures ofthe drawings not only the opposed ends of adjacent staves but also in aslight degree, laterally adjacent staves. Although my spacer elementused in connection with the con ventional silo stave it may be seen thatslight indentations 15 and 16 must be made in the adjacent staves toprovide engagement portions for the ventilator member.

1 have shown a specific spacer element to be interposed between thestave members but I do not wish to be limited to this particular forminasmuch as other Forms might be used to accomplish the same result.

Although I have referred to the stave members 10 as those used in theconventional silo, l merely make this as a general statement and wish,in the more perfect application for my spacer element, to use it inconjunction with stave members having their opposed ends sloped to anangle of appronh niately forty-five (45} degrees, as shown at 1? and 18in Figure 2, this construction of the end portions of the stave memberspr venting rain partially from beating; through the entilatii portion.

i fhat I. claim is:

j 1 A ventilated corn crib including aplurality oi vertically disposedstaves arranged end to end in superposed courses, and grated ventilatormembers disposed between adjacent staves.

2. A ventilated corn crib including a plurality of vertically disposedstave-s arranged end to end in superposed courses and in break jointrelation, means engaging the opposed ends of related staves and disposedtherebetween in such manner as to form a ventilating opening therein andsupporting means encircling the crib.

3. A ventilated corn crib including a plurality of vertically disposedstaves arranged end to end in'superposed courses, said staves having anelongated comparatively thin and narrow body with recesses formed in theends thereof, and ventilating members disposed between the opposed endsof adjacent staves and engaging said recesses.

4. A ventilated corn crib including a plu- JOHN H. IREY.
